MILTON H. EVANS, OF JOPLIN, MISSOURI.

COMBINATION STERILIZER AND IRRIGATOR.

To all whom it may concern:

Be it known that I, MILTON H. EvANs, a citizen of the United States ofAmerica, residing in Joplin, in the county of Jasper and State ofMissouri, have invented certain new and useful Improvements in aCombination Sterilizer and Irrigator, of which the following is aspecification.

My invention relates to combination sterilizers and irrigators, andespecially to a certain novel construction, hereinafter fully described,by means of which I provide an extremely simple, compact and portablearticle of this class.

In the drawing: Figure 1 is a perspective view of my invention in use asa sterilizer; Fig. 2 is a similar view, with cover removed and tubeattached, in use as an irrigator; Fig. 3 is a perspective view of thecover portion reversed for use as a pan; and Fig. 4 is a like view of aperforated tray adapted to fit inside the sterilizer.

Referring to the drawing, the letter B designates the main receptacle,preferably constructed of material to resist rust, heat and chemicals,having an opening a in one end and a tap "a in the opposite or base endI) (Fig. 2). The opening a is designed to admit the sterilizer tray,hereinafter described, and at the same time to permit the mainreceptacle B to hold water to be converted into steam in the sterilizingprocess. The tap at permits the escape of steam, and when the instrumentis used as an irrigator, accommodates a tube as illustrated in Fig. 2.

A cover portion A fits over the sterilizer, as shown in Fig. 1, saidcover being adapted for use as a pan when reversed (Fig. 3). The pan Ahas attached thereto at either end handles C, preferably hinged asillustrated with strips of metal m and rivets 0.

Serial No. 430,189.

X'represents a perforated sterilizing tray for the instruments,dressings, towels, etc., adapted to fit into the receptacle B throughthe opening a as above indicated. The tray X is fitted with handles 0and knobs or legs L.

An additional feature of novelty of my invention consists in the movablehandles O preferably hinged to both ends of the main receptacle B. Inthe drawing this is accomplished by means of strips of metal m andrivets 0. The handles C are turned down and used as legs (Fig. 1) forsterilizing, and the handle at the upper end may be used to hang theinstrument up for irrigating, or in the latter case, when placed upon asupport, the lower handle may serve as a supplemental base (Fig. 2).

It is understood that I do not limit myself to the precise detailsillustrated, but may vary my construction within the scope of theclaims.

I claim:

1. A surgical appliance comprising a main receptacle having a diagonalopening at one end and a tap at the other, movable handles at both ends,said handles being adapted for use as legs, a supplemental tray adaptedto fit inside the main receptacle, and a cover for closing said diagonalopening.

2. A surgical appliance comprising a main receptacle provided with anopening at one end and a tap at the other, movable handles at both ends,said handles being adapted for use as legs, a supplemental tray adaptedto fit inside the main receptacle, and means for closing said opening.
